Drinking just two of coffee a day can significantly improve your sex life, new research suggests.

A study at the University of Texas showed that men who drink two cups of coffee a day were 42 percent less likely to suffer from erectile dysfunction compared to those who do not have this habit.

The article of the American scientific journal PLoS One says that scientists have examined 4,000 men who drink caffeinated beverages including coffee, tea, carbonated and energy drinks, and noted that the results were the same regardless of weight, age or blood pressure patients.

Experts believe that this is because the caffeine starts a chemical reaction that increases blood flow to the penis, relaxing the muscles.

However, two cups of the daily limit, as the scientists noticed that the third cup of this drink reduces the effects of caffeine.

Also, it turned out that the habit does not have any effect on men who suffer from diabetes.
